This study identified blood-entering components of Anshen Dropping Pills and explored their anti-insomnia effects and mechanisms. The main blood-entering components of Anshen Dropping Pills were detected and identified by UPLC-Q-TOF-MS/MS. The rationality of the formula was assessed by using enrichment analysis based on the relationship between drugs and symptoms, and core targets of its active components were selected as the the potential anti-insomnia targets of Anshen Dropping Pills through network pharmacology analysis. Furthermore, protein-protein interaction(PPI) network, Gene Ontology(GO) enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed on the core targets. An active component-core target network for Anshen Dropping Pills was constructed. Finally, the effects of low-, medium-, and high-dose groups of Anshen Dropping Pills on sleep episodes, sleep duration, and sleep latency in mice were measured by supraliminal and subliminal pentobarbital sodium experiments. Moreover, total scores of the Pittsburgh sleep quality index(PSQI) scale was used to evaluate the changes before and after the treatment with Anshen Dropping Pills in a clinical study. The enrichment analysis based on the relationship between drugs and symptoms verified the rationality of the Anshen Dropping Pills formula, and nine blood-entering components of Anshen Dropping Pills were identified by UPLC-Q-TOF-MS/MS. The network proximity revealed a significant correlation between eight components and insomnia, including magnoflorine, liquiritin, spinosin, quercitrin, jujuboside A, ginsenoside Rb_3, glycyrrhizic acid, and glycyrrhetinic acid. Network pharmacology analysis indicated that the major anti-insomnia pathways of Anshen Dropping Pills involved substance and energy metabolism, neuroprotection, immune system regulation, and endocrine regulation. Seven core genes related to insomnia were identified: APOE, ALB, BDNF, PPARG, INS, TP53, and TNF. In summary, Anshen Dropping Pills could increase sleep episodes, prolong sleep duration, and reduce sleep latency in mice. Clinical study results demonstrated that Anshen Dropping Pills could decrease total scores of PSQI scale. This study reveals the pharmacodynamic basis and potential multi-component, multi-target, and multi-pathway effects of Anshen Dropping Pills, suggesting that its anti-insomnia mechanisms may be associated with the regulation of insomnia-related signaling pathways. These findings offer a theoretical foundation for the clinical application of Anshen Dropping Pills.

Aim To investigate the effect of ACSL4 on the malignant biological behavior of esophageal cancer cells and gefitinib resistance by regulating FASN,and to explore the related mechanism.Methods Thirty-five fresh esophageal cancer tissues and adjacent nor-mal tissues,and 30 esophageal cancer tissues with ge-fitinib resistance were collected.The expressions of ACSL4 and FASN were detected by qRT-PCR and im-munohistochemistry.The expression levels of ACSL4 and FASN in human normal esophageal cells HET-1 A,esophageal cancer cell lines ECA109,EC9706,TE-1 and TE-1/GR were detected by qRT-PCR.Cells in each group were constructed by liposome transfection technique,and the drug resistance and proliferation a-bility of cells were detected by cloning and CCK-8 as-say,cell apoptosis was detected by flow cytometry,cell invasion ability was detected by Transwell,and EMT pathway protein expression was detected by Western blot.Results Compared with adjacent normal tis-sues,the expression of ACSL4 and FASN genes in cancer tissues increased,and there was a positive corre-lation.The expression of ACSL4 significantly increased in ECA109,EC9706 and TE-1 cells compared with HET-1 A cells.With the increase of gefitinib concen-tration,the expression of ACSL4 in TE-1 cells gradually increased,and the expression of ACSL4 in TE-1/GR cells was higher than that of TE-1.Compared with the control group and the si-NC group,the cell proliferation and invasion ability of si-ACSL4 group decreased,the number of apoptosis increased,the expression of E-Cadherin increased,and the expression of N-Cadherin,Vimentin and β-catenin decreased.The response ex-periment showed that compared with the si-ACSL4 group and the si-ACSL4+oe-NC group,the cells in the si-ACSL4+oe-FASN group increased drug resistance,increased proliferation and invasion ability,decreased apoptosis number and decreased expression of E-Cad-herin.The expressions of N-Cadherin,Vimentin and β-catenin increased.Conclusions By down-regulating the expression of FASN,ACSL4 reverses the resistance of esophageal cancer TE-1/GR cells to gefitinib and in-hibits the proliferation,invasion and accelerates apopto-sis of TE-1/GR cells,which may be related to the regu-lation of EMT signaling pathway.

Objective To investigate the expression level and diagnostic value of serum cysteine protease inhibitor S(CST4)in patients with gastric cancer.Methods Clinical data of 115 patients with suspected gastric cancer who complained of gastric discomfort were retrospectively analyzed,and they were divided into benign disease group(n=50),precancerous disease group(n=26)and gas-tric cancer group(n=39).The levels of serum CST4,carcinoembryonic antigen(CEA),carbohy-drate antigen 19-9(CA19-9)and carbohydrate antigen 72-4(CA72-4)were analyzed in the three groups.The positive rates of CST4 among the three groups were compared.Binary Logistic regression analysis was used to screen for independent risk factors for gastric cancer occurrence.The receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of CST4 in gastric cancer.Results The positive rate of CST4 was 6.00％(3/50)in the benign gastric disease group,30.77％(8/26)in the gastric precancerous lesion group,and 66.67％(26/39)in the gastric canc-er group.The positive rate of CST4 in the gastric cancer group was higher than that in the gastric pre-cancerous lesion group and the benign gastric disease group(P＜0.05).The results of binary Logistic regression analysis showed that advanced age,high levels of serum CST4 and high levels of CEA were independent risk factors for gastric cancer occurrence(P＜0.05).The area under the curve(AUC)for CST4 alone in diagnosing gastric cancer was 0.847(95％CI,0.760 to 0.934),with an optimal cut-off value of 94.6 U/mL,the Youden index of 0.638,sensitivity of 71.8％,and specificity of 92.0％.The AUC for the combined diagnosis of gastric cancer using CST4,age and CEA was 0.959(95％CI,0.919 to 0.992),with sensitivity of 94.9％and specificity of 86.0％.Conclusion As a novel se-rum marker,CST4 has high predictive value in the auxiliary diagnosis of gastric cancer.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Objective To construct a regulatory network of competing endogenous RNA(ceRNA)with prognostic value for bladder urothelial carcinoma(BLCA),and analyze the relationship between key messenger RNA(mRNA)and immune function.Methods The UCSC Xena database was used to download mRNA expression data from 404 BLCA patients and 28 normal individuals and key mRNAs were screened by differential analysis.ENCORI database was utilized to search microRNAs(miRNAs)that bind to key mRNAs and all long non-coding RNAs(LncRNAs)that bind to miRNAs.The expression data of miRNA and LncRNA were downloaded from TCGA database,co-expression analysis was performed to identify key mRNA with all miRNAs and miRNA with all LncRNAs,and thus key miRNAs and LncRNAs were screened out.Survival analysis was conducted based on the differences in expression levels of these key mRNAs,miRNAs,and LncRNAs between tumor patients and normal individuals,and finally a ceRNA regulatory network was constructed.The correlation between key mRNAs and immune cells,immune checkpoints(CD274,PDCD1 and CTLA4),and immune cell marker genes(IG)was analyzed using the TIMER 2.0 database.Results A total of 22 key mRNAs were screened,with the most significant difference being proline 3-hydroxylase 4(P3H4).The expression of P3H4 in patients with BLCA was high,and survival time was shorter in patients with high expression.A sum of 33 miRNAs and 14 LncRNAs were screened using the key mRNAs as the central link.Through co-expression analysis and survival analysis,hsa-miR-151a-3p and MIR100 HG were identified as the key miRNA and key LncRNA with prognostic value.The differences in the above analysis results were statistically significant(all P＜0.05).Based on these findings,a ceRNA regulatory network consisting of 1 mRNA,1 miRNA,and 1 LncRNA was constructed.Immunoassay firstly revealed a significant positive correlation between double positive T cells and P3H4 expression in the tumor microenvironment of BLCA.Moreover,there were 3 types of immune cells(tumor-associated neutrophils,and tumor-associated macrophages,dendritic cells),3 immune checkpoints(CD274,PDCD1,CTLA4),and 15 IGs with significant correlation with P3H4.These differences were statistically significant(all P＜0.01).Conclusion This study could help to reveal the progression mechanism of BLCA.The constructed ceRNA network and immune analysis can offer new insights into potential biological targets and immunotherapy directions for the diagnosis,treatment,and prediction of BLCA patients.

Cancer stem cells (CSCs), a small subset of cells in the tumor bulk with the ability of self-renewal and differentiation, are the key to tumor occurrence, metastasis, drug resistance and relapse. CSCs are resided in a specific microenvironment, and their number maintenance, self-renewal and differentiation are precisely regulated by the microenvironment, and the immune microenvironment is one of the most critical microenvironments for CSCs. In recent years, tumor immunotherapy has achieved great success, but drug resistance and recurrence are frequently occurred after immunotherapy. Compared with non-CSC tumor cells, CSCs harbor stronger immune escape ability, and their roles in tumor immune escape are increasingly followed. In this review, we described the discovery history and lineage sources of CSCs, focused on immune cells in the CSC microenvironment, such as tumor-infiltrating lymphocytes, tumor-associated macrophages, and tumor-associated dendritic cells, and analyzed the mechanism of CSC-immune cell interaction. Intervention strategies targeting CSCs and their immune microenvironment are also described. With the development and application of advanced technologies such as CSC-immune cell co-culture, single-cell sequencing and lineage tracing, the immune escape of CSCs can be suppressed by targeting the interaction between CSCs and immune cells or reversing the immunosuppressive microenvironment, which is expected to provide potential solutions to the problems of drug resistance and relapse in tumor immunotherapy.

Objective: human cysteine protease inhibitor S; helicobacter pylori antibody typing; human epidermal growth factor receptor 2 ; gastric cancer; pathological stage; gastric cancer lymph node metastasis Methods: A total of 150 gastric cancer patients admitted to Chaohu Hospital Affiliated to Anhui Medical University for surgery from December 2021 to December 2023 were selected as the study objects. Serum CST4 and HP antibody typing were performed before surgery, and HER2 expression levels in gastric cancer tissues were detected by immunohistochemistry after surgery. The clinicopathological data of gastric cancer patients with different serum CST4, HP antibody types and HER2 expression were compared and the correlation was analyzed. ROC curve was used to compare the predictive value of single and combined detection of serum CST4, HP antibody typing and HER2 expression in lymph node metastasis and TNM staging of gastric cancer. Results: Patients with CST4, HPI and HER2-positive expression had deeper tumor invasion and were more likely to develop distant lymph node metastasis, and TNM stages were more likely to occur in Ⅲ and Ⅳ stages(P<0.05). Meanwhile, patients with CST4 positive expression were more likely to have vascular and nerve invasion(P<0.05). In patients with HPI positive expression, tumors were more likely to occur in the cardia and the bottom of the stomach, and the tumor diameter was larger and vascular invasion was more likely(P<0.05), while HER2 was negatively correlated with the degree of tumor differentiation, and the tumors were more likely to occur in high and secondary differentiation(P<0.05). ROC curve analysis showed that the AUC of single and combined detection of serum CST4, HPI and HER2 expression to predict lymph node metastasis of gastric cancer were 0.780, 0.676, 0.611 and 0.872, respectively(P<0.05). The AUC for TNM stage diagnosis of gastric cancer were 0.762, 0.635, 0.613 and 0.801(P<0.05), respectively. The diagnostic efficiency of combined detection was higher than that of single detection. Conclusion The expression of CST4, HPI and HER2 in serum is closely related to the depth of tumor invasion, lymph node metastasis and TNM stage. The expression of CST4, HPI and HER2 in serum can be used as an important predictor of lymph node metastasis and TNM stage in gastric cancer patients, providing a new idea for clinical diagnosis.
